Metal Detectors
Metal detectors are a frontline defence against contamination on a food processing line, identifying ferrous, non ferrous and stainless steel in product and rejecting affected packs automatically. Within the inspection and quality control stage they sit at critical points to catch metal that enters from machinery wear, raw materials or handling. Aperture size, sensitivity to each metal type and how the product effect is handled decide performance for a given product. Wet, salty and metallised packs are harder to inspect and need the right technology. This category carries new and used metal detectors in conveyor and gravity fall formats, with aperture, sensitivity and condition detailed by verified sellers.

Metal Detector Types
Metal detectors vary by how product passes through them and by the products they suit. The main formats are below.
Conveyor metal detectors
These detectors inspect packed and loose product carried through the aperture on a belt. They are the everyday choice for finished and in process packs on a line.
Gravity fall metal detectors
Gravity units inspect free falling powders and granular product through a vertical aperture. They suit bulk ingredients and free flowing materials before packing.
Pipeline metal detectors
Pipeline detectors inspect pumped liquids, slurries and pastes as they flow through the pipe. They suit wet products handled in a closed system.
Pharmaceutical and small aperture detectors
Small aperture detectors give high sensitivity for tablets, capsules and small packs. The tight aperture concentrates the field for detecting very small metal fragments.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
Metal detection guards food, beverage and pharmaceutical lines against metallic contamination. The common uses follow.
Finished pack inspection
Conveyor detectors check finished packs for metal before they leave the line. This protects consumers and supports the producer's safety controls.
Ingredient and powder screening
Gravity detectors screen powders and granular ingredients before they enter the process. Catching metal early protects downstream equipment and product.
Liquid and paste inspection
Pipeline detectors inspect pumped liquids and pastes in a closed flow. This suits products that cannot be checked on a belt.
Small format product checks
Small aperture detectors inspect tablets, sachets and small packs with high sensitivity. The tight field detects fragments that a large aperture would miss.
Benefits from Machinery Masters
This part of the inspection and quality control range covers detection for packs, powders and pumped product.
A format for every product flow
Conveyor, gravity fall and pipeline units sit side by side, so the machine that suits how your product moves is one search away.
Proven sensitivity without the new price
A serviced used metal detector protects the line to the same standard as new for considerably less. Aperture, sensitivity and condition appear on each listing so comparison is straightforward.
Run test spheres before you buy
Ask the seller to pass ferrous, non ferrous and stainless test spheres through your product and watch the reject fire. A unit that proves its performance will stand up to audits and retailer codes.
Frequently Asked Questions About Metal Detectors
Ask for a recent performance record or a live pass with certified test pieces at the sensitivity your specification demands. Confirm the reject mechanism fires reliably and the control and coil are sound. A detector that cannot prove its sensitivity on demand will fail an audit.
The aperture must be large enough to pass your biggest pack but no larger, since a smaller aperture gives higher sensitivity. An oversized aperture weakens the field and reduces the smallest metal you can detect. Match the aperture closely to your largest product for the best detection.
Wet, salty and metallised products create a product effect that makes detection harder. Modern detectors compensate for this, but you should confirm the machine handles your specific product. Ask the seller whether it was used on a similar product with good sensitivity.
The product form decides the type, with conveyor units for packs, gravity units for powders and pipeline units for pumped liquids. Match the detector to how your product moves through the line. Using the wrong format compromises both detection and handling.
Qualifying listings carry a finance option, which spreads the cost of a detector or a complete contamination control stage. Look for the flag on the listing itself. You can also raise finance with the seller during your enquiry to see what suits your budget.
